Long-term prognosis in patients undergoing redo-isolated aortic valve replacement

Area of Science:

• Cardiology
• Cardiac Surgery
• Interventional Cardiology

Background:

• Redo aortic valve replacement (AVR) is complex, with various techniques available.
• Comparing clinical outcomes of different redo AVR methods is crucial for patient management.

Purpose of the Study:

• To evaluate and compare clinical outcomes after redo AVR using sutured valves, valve-in-valve transcatheter AVR (ViV-TAVR), and sutureless valves.
• To assess the incidence of postoperative atrial fibrillation (POAF) among these redo AVR strategies.

Main Methods:

• A cohort of 113 consecutive patients undergoing redo AVR between August 2010 and March 2020 was analyzed.
• Patients were treated with either ViV-TAVR, redo-sutured AVR, or redo-sutureless AVR, with treatment decisions made by a heart team.
• Propensity-adjusted analysis was used to compare postoperative outcomes.

Main Results:

• Postoperative analysis revealed a higher incidence of new POAF in the redo surgical aortic valve replacement group compared to the redo-sutureless group (p=0.04).
• Follow-up outcome analysis did not reveal significant differences among the groups regarding other clinical outcomes.

Conclusions:

• Patients undergoing redo-sutureless AVR experienced a higher incidence of POAF compared to those undergoing redo-sutured AVR.
• The study highlights potential differences in early postoperative complications between redo AVR techniques.
